Today Reactable Systems released SNAP drum machine for iOS and Android! This one offers a way to generate unique patterns in a fairly simple way. It is aimed explicitly at casual users, but I had a lot of fun with it. The Android version is surprisingly feature complete, including both MIDI and Ableton Link. MIDI input and output require an IAP, but I can't tell you how much it costs because iTunes is fucking up hard right now and won't accept the IAP request.

SNAP iTunes Description:

From music producers to casual users, SNAP will help you create great drum patterns in any musical style, on the fly, with your fingertips.

SNAP can also help you in the studio, by providing seamless variations of your patterns, under your complete interactive control. Program or load drum patterns, store your favorite variations, and export them to your DAW, all on a continuous and free-flowing loop/fashion.

SNAP is also a powerful tool for your live sessions, providing you with subtle or radical changes, from sudden drops to ecstatic crescendos, all fully and instantaneously controllable under your fingertips.

SNAP can communicate with your music apps, drum machines, DAWs and other musical equipment via MIDI OUT and Ableton Link. SNAP’s full integration with Native Instrument’s Maschine Jam, allows it to communicate bidirectionally to become its “drumming brain”. Compatibility with other control devices will be rolled-out progressively.

SNAP provides:
- 8 drum voices, each one with its own continuous density controller.
- 4 different intelligent syncopation/reinforcement algorithms, independently selectable for each drum voice.
- MIDI IN and OUT integration (Available as an In-App purchase).
- Ableton Link synchronization support.
- 8 snapshot slots for storing, recalling and updating drum patterns on the fly.
-16 specially designed drum kits
- Sessions and patterns covering different styles to get you started right away.

Dear lord you guys a whiny. This is an awesome drum sequencer. The variation sliders are a brilliant idea. The whole thing is midi mappable ( kind of a kludge, needed to download NI Jam editor to figure out midi cc. But it’s a great app...
